Oops -- my bad.  I misread the error messages.  All that needs to happen
is to enclose the multiple notes in braces, to make a single music
expression.  Multiple notes outside of braces make multiple music
expressions which aren't allowed.

This code works:

\version "2.10.19"
\paper {ragged-right = ##t}

#(define-markup-command (segue layout props tosong)
    (string?)
    (interpret-markup layout props
        (markup #:small #:column ("segue to"  #:italic tosong))
    )
)

\score {
{c'1 c' c' c' c'1_\markup \segue #"Something Else"}
}
